Abstract

To Check The Ions Present In The Toothpaste And Determine The Quality.

Theory

Every toothpaste contains the following ingredients: binders, abrasives, subsers, humectants, flavours, sweeteners, fluorides, tooth whiteners, a preservative and water. Binders thicken toothpaste- they prevent separation of the solid and liquid component, especially storage. They also effect the speed and volume of foam production, rate of flavor release and product dispersal, the appearance of toothpaste ribbon on the toothbrush. Some binders are gum solid alignate, methyl cellulose, carrageen and magnesium aluminium silicate

Colour Of The Paste- White

To Check The Ions Present in Toothpaste

Chemical Reaction

1. CO3 +MgSO4 → MgCO3 + SO4 (white ppt.)

2. CO3 + 2CH3COOH → (CH3COO)2Ca + H2O
(CH3COO)2Ca + (NH4)2C2O4 → 2CHCOONH4 +CaC2O4

3. NaHPO4 + MgCl2+ NH4OH → Mg(NH4)PO4 + 2NaCl + H2O

4. I+ AgNO3 →NO3+AgI (yellow ppt.)

5. (COOH)2 + 2CH3COONa → NO REACTION

6. Pb + 2KI→ NO REACTION

7. MgCl2 + NH4OH+ (NH3)2HPO4 → Mg(NH4)PO4 + 2NH4 +H2O

To Check The Ions Present In The Toothpaste

IONS PRESENT:- Mg, I, PO4, Ca, CO3

Chemical Reactions

1. CO3 +MgSO4 → MgCO3 + SO4
(white ppt.)

2. CO3 + 2CH3COOH → (CH3COO)2Ca + H2O
(CH3COO)2Ca + (NH4)2C2O4 → 2CHCOONH4 +CaC2O4

3. NaHPO4 + MgCl2+ NH4OH → Mg(NH4)PO4 + 2NaCl + H2O

4. I+ AgNO3 →NO3+AgI
(yellow ppt.)

5. (COOH)2 + 2CH3COONa → NO REACTION

6. Pb + 2KI→ NO REACTION

7. MgCl2 + NH4OH+ (NH3)2HPO4 → Mg(NH4)PO4 + 2NH4 +H2O

2. CO3 + 2CH3COOH → (CH3COO)2Ca + H2O
(CH3COO)2Ca + (NH4)2C2O4 → 2CHCOONH4 +CaC2O4

3. NaHPO4 + MgCl2+ NH4OH → Mg(NH4)PO4 + 2NaCl + H2O

4. I+ AgNO3 →NO3+AgI (yellow ppt.)

5. (COOH)2 + 2CH3COONa → NO REACTION

6. Pb + 2KI→ NO REACTION

7. MgCl2 + NH4OH+ (NH3)2HPO4 → Mg(NH4)PO4 + 2NH4 +H2O

Conclusion

Hence after testing different samples of toothpaste, we find that colgate has all necessary for stronger and whiter teeth
